To ALL WHOM rr MAY eoNenRN: f

Be it knownthat I, .I O'IIN GfKIMBERLLof Dryden, in the county of Tompkins, and State of New York,

have invented a new and useful Improvement in Horse Hay-Rakes; and I do herehydeclare that the followingv is a full, clear, and exact description thereof, which will enable others skilled in. the art to malte and use the same, reference being had to the accompanying drawings, forming a part ot' this specification, in'which- Figure l is a vertical longitudinal section of the rake of my invention, taken in the line :u fr, iig. 2.

Figure 2 is a top view of the same. f

Figure 3 is a transverse section of the rake-head, showing the mode of connecting the raketeeth.

Figure 4 is a side view of the same.

Similar letters of reference indicate like parts.l

This invention relates to new and useful improvements in steel-wire toothed hay-Takes, and consists in the arrangement of a lever, in connection with the rake-head and the draught for unloading, and otherwise facilitating the working of the rake; and also in a novel mode of attaching the teeth to the rake-head, to secure them firmly in place without lateral movement, while they preserve their independent action vertically.

The construction ofthe frame is veryr simple. A'A are the driving-wheels, and B the axle, behind which is suspended the rake-head C, on .the pivots a a,- for raising and lowering in the usual way. D is the drivers seat, mounted on the axle, a. litt'le'on one side ofthe middle. E E are the thills, connected bythe cross-bars or braces F F. 'A small central beam,P, connects the aile B and the rear cross-bari'. The beam P is slotted vertically, for receiving av'managing lever,- e, which passes through the slot, and has its fulcrum at e, in the beam I?. Above the fulcrum and the be'a-n'rI, a draught chain, `CZ, is attached by an adjustable clevis, u, to the lever e, which chain-passcs over the brace-bars F F', and connects with the whiiiie-tree G. I'I'o the lower end of the lever c is attached a lifting chain, g, which 'connect-s with a spiral spring, 7L, placed under the aXleB, and hence runs to a segment guidelblock, H, which is fastened on the rake-head C, and then passing forward over the axle B, is fastened to thelever c. The chain g passes around' a groove in the periphery of the segment guide, and isfast-cned to iti'for 'the purpose of'holding and turning the rake-head, and lifting the teeth to unload when the managing lever c is operated. The lever c works alongside of a. segmental iron guide-bar, extending from the ren-r of the axle B to the frontof the cross-bar F, and the lever Vtraverses on the guide-bnr with .a guide-loop, t'. On thel inside of the guide-bar k, at the back end, are two or more notches, which catch the lever' when it is depressed to lower the rake-teeth to the ground, and in which it is held in place by means of a side spring, m, on the outside Vof the segment guide k. The lever e has on it a stop projection, n, which bears on the axle B, and prevents excessive strain on the spring h, when the lever is depressed to lower the rake-teeth. The wire teeth o o are attached in a novel manner to the rake-head, so that while they have a limited vertical play, they cannot move laterally. The upper end of the teeth o o are bent, and fitted in circular grooves s s, turned in the rake-head C, passing through two staples, 'u v. One side of each of the staples passes through the rake-head and forms a bolt which is firmly secured in place by screw-nuts u u.. i The extremities of the rake: teeth are turned up a little to catch in the staple and hold them in place in the simplest possible way. Between the teethare the clearing-bars p p, which project from the axle B under the rake-head C, and support it in the ordinary way.

It willrbe observed that the draught is directly upon the lever c, which is in a fixed position when the rake is at work, being held in place in the notch on the segment guide 7c by the spring m. When the rake is filled with hay, it is unloaded by the release of the lever at the right hand of the driver, who gives it aslight side pressure. The draught pulls the lever forward, and lifts the rake instantly by-means of the chain g, over the segment Il. The-draught is relieved when the hay drops, and the weight of' the rake-head and teeth immediately brings the lever back to its place, where it is' again 4secured in the notch on the segmentguide le by the spring m to proceed with the work. 'lhe rake-teeth are held to their work on the ground'by the lower part of the chain g, connected with the lower end of the lever c, while, at the same time, the spira-l spring m takes oil' the rigidity, and allows a little play to the rake-head to adapt it to unevenness ofvthe ground.

Having described the construction of my invention, what I claim as new, and desire to secure by Letters Patent, is-

The continuous chain g, provided with an intermediate.spring 1,\in combination with the lever c and rakehead C, substantially as described for the purpose specified. I

JOHN G'. KIMBERLIN.
